|What is meant by Morse Code?|

Morse Code is a system for communicating text
over long distances. Before telephones and the
Internet allowed people in different locations to
speak to each other, they had to rely on the
electrical telegraph for near-real time
communication. An operator would use a telegraph
to send a series of electrical pulses to another
operator's telegraph receiver. Morse Code was
developed as a system of "dits" and "dahs"--short
and long pulses--that could be sent via telegraph
and stood for letters in the alphabet. Letter by
letter, telegraph operators would translate and
tap out messages in Morse Code that were received
and translated back into natural human language.
This system allowed people to communicate across
continents and oceans almost instantly at a time
when most other long-distance communication
happened by mail and was considerably slower.
Morse Code is named for Samuel Morse, who was
instrumental in developing the electronic
telegraph system in the 1830s. You can read more
about Samuel Morse, Morse Code, and the electronic
Morse code is kind of like another language in
which each letter or number of the alphabet or
numerical system is represented by sometimes dots
and dashes, or sound in which it can be a short
beep or sustained tone.
Morse Code is a code created by a man named
Morse and was used as a form of communication back
in the days in which communication was by
telegraph and did not have the precision to send
the density of information that modern telephone
(let alone internet) can do. The code is used to
take a series of clicks of different lengths and
turn them into letters, which are then used to
spell words and otherwise make up a language.
Morse code is a way to transform letters into a
series of dots and dashes, or short beeps and long
beeps. That's all it is. Nowadays we send very
complicated signals through many data lines, but a
long time ago this was difficult, and the easiest
signal to send was an "on" signal. When you
connected the circuit, it beeped, and people came
up with a code of long beeps and short beeps to
encode different letters. Each letter has a
specific combination of short and/or long beeps,
and if both people communicating know the code (or
combination), then messages could be sent!
